Thread: 16/20VE Shim Clearance

When the valve clearance says No.1 cylinder front and No.2-4 back and whole, what do those mean?

For example, I have sr20ve cams.
Cylinder 1 would have .25 and Cylinders 2-4 would have .16? (when cold)

SR16VE.N1 has 0.17mm +-0,05mm for intake and 0.37mm +-0,05mm for exhaust
P12 SR20VE 20V has 0.20mm +-0,05mm intake and 0.34mm +-0,05mm for exhaust

Mazworx claimed that his N1 exhaust cam has 0.40-0.45mm. This matches with N1 specs when engine is warm.

I believe now it's more clear to everybody.

So with my sr20ve, I would use:

.25mm intake and
.32mm exhaust?

This is cold.

bump...also, all these are in MM, not inches, right?

and whats front back and whole?

no one?
